Tool to archive Gluster Changelogs

Changelogs are not required for Geo-replication once the Changelogs are consumed and synced to Slave. This tool helps to archive the changelogs which are already consumed.

Usage

# When using python2
mkdir <archive_dir>
python2 archive_georep_changelogs_p2.py <brick_path> <archive_dir>
cd <archive_dir>
tar cvzf <archive>.tar.gz <archive>/

# When using python3
mkdir <archive_dir>
python3 archive_georep_changelogs_p3.py <brick_path> <archive_dir>

Example:

mkdir /backups/changelogs_bricks_b1_20170119
python3 archive_georep_changelogs_p3.py /bricks/b1 /backups/changelogs_bricks_b1_20170119

How it works?

• List xattrs for given brick path
• If xattr name ends with .stime, read the xattr value(Repeat this for all the stime xattrs)
• Gets Timestamp from brick status files of Glusterfind
• Archive all changelogs files if Changelog file Timestamp is less than min of stime values collected in previous steps.
• The python3 version of the script creates a tgz archive and adds all changelog files to it.
